A LITERARY REVIEW ON THE EFFECT OF GARA VISHA WITH SPECIAL REFERENCE TO FOOD PRESERVATIVES AND ADDITIVES

The ever-growing era of technology has given us plenty of boons but has also burdened us with innumerable banes, one of which is the poisonous effect of food additives and preservatives. Reports show that the dependency of an average man on preserved and packed food is expected to show an increase of 8% in just the span of 5 years i.e. 2015-2020, this is directly proportional to the increase in number of various disorders like Kushtha (skin ailments), Raktachapa (Blood pressure variations). The long term usage of food preservatives and additives can be considered as Gara Visha, the type of poison which impacts the body of an individual on long term usage. This usage of viruddha (preservatives and additives) leads to formation of Gara Visha in the body of an individual.

XPS Study of Poisoning Mechanism of O2 on LaNi4.7Al0.3 Oxygen

In this paper, LaNi4.7Al0.3 alloy samples were obtained via melting in middle frequency influence fire .In addition, The alloy pellets were milled for absorbing and desorbing Hydrogen ability study, The P-V-T measurement provided us with poisonous effect on the oxidation of LaNi4.7Al0.3.To understand the poisoning mechanism of O2 on LaNi4.7Al0.3, the X-ray photoelectron spectroscopy (XPS) was introduced to analyzed the process of poisoning of LaNi4.7Al0.3 alloy, Which revealed the changes of the valence of the elements of the alloy LaNi4.7Al0.3 poisoned by O2.

The action of sodium azide on cellular respiration and on some catalytic oxidation reactions

Azoimide, HN 3 , was prepared by Curtius in 1890. Loew (1891) studied the effect of this acid and of its sodium salt on a great variety of organisms such as bacteria, moulds, algae, seedlings of plants, ciliates, worms, Crustacea, insect larvae, and vertebrates. He found it toxic to these organisms but, while some of them died within 2 or 3 hours in 0·5% solution of this salt, other organisms were killed only after 20-40 hours or even 4-6 days by 0·1% solution of NaN 3 , and ciliates withstood this concentration for even 12 days. According to Loew, the toxic effect produced by this salt is due to its decomposition accompanied by the liberation of ammonia. This inter­pretation was not accepted by other workers, and it is now generally accepted that the poisonous effect produced by this substance is due to the action of the nitrogen anion. N ║ N—. N/

STUDIES ON THE TOXIN PRODUCTION OF THE SHIGA BACILLI

1. The S, R, and Rn variants of the Shiga bacillus are equally toxic. 2. The effect of the toxin upon rabbits is the same, whether it is derived from filtrates of broth cultures (3 to 6 days old), or is obtained by autolysis of the killed bacteria, grown on agar surface. Rabbits show in both cases prostration, loss in weight, paralysis, and diarrhea. 3. When the toxin is heated to 80°C. for 1 hour, its poisonous effect nearly disappears, but its immunizing ability is unaltered. This heated toxin induces a formation of antitoxin, which can protect against the unheated toxins. 4. The anatomical changes observed in the spinal cord (degeneration of the motor neurons) and in the cecum (hyperemia and hemorrhages) are in agreement with the statements of previous authors. Furthermore, the toxin causes hyperemia and hemorrhages in the heart, hyperemia and degeneration in the kidneys and the liver.

On the part played by benzene in poisioning by coal gas.

In a recent paper Vahlen has maintained that a difference exists between the poisonous action of coal gas and of carbon monoxide, and Kunkel has also drawn attention to a similar difference in the case of frogs. In the course of a research which I was undertaking in University College for other purposes, at the suggestion of Professor h Starling, I have come across facts which may serve to explain the difference noted by these observers. My first object was to investigate the effect of deprivation of oxygen on the fatigue curve of muscles. To this end, a muscle was hung up in a closed chamber and the atmospheric air driven out by a stream of some other gas. When coal gas was used for this purpose, it was noticed that the muscle rapidly went into rigor mortis , whereas, in nitrogen, it remained excitable for many hours. I set myself, therefore, to find out which constituent of the coal gas was responsible for this poisonous effect.
